In order for a secondary power supply to be compliant, what must it provide?

A secondary power supply in fire alarm systems is essential for ensuring that the system remains operational during a power outage or failure of the main supply. Compliance requirements often dictate that this secondary source must provide uninterrupted power transfer. This means that when the primary power source is lost, the secondary power must seamlessly take over without any interruption in the supply of electricity to the fire alarm system. Uninterrupted power transfer is crucial because even a brief loss of power could compromise the effectiveness of the fire alarm systems, potentially delaying alarm notifications and responses in an emergency situation.

Ensuring uninterrupted power transfer helps maintain the functionality of life-saving systems, providing reliable notifications to occupants and responders during a fire or other emergencies.
